SPECIFICATION forming part of Letters Patent No. 380,178, dated March 27, 1888. Application niednprn 4, les?. serial N6. 233,547. (Model.)

To all whom it may concern.-

Be it known that we, PERRY BROWN and WILLIAM TRABUE, both citizens of the United 'States of America, residing atv Louisville, in

` specification, reference being had therein to the accompanying drawings, in which- Figure 1 is a perspective side view of our vise; Fig. 2, a central vertical longitudinal section; Fig. 3, a perspective view of the movable jaw, screw, and nut; and Figs. 4, 5, and 6 are details which will be more fully referred to hereinafter.

This improvement relates more,particularl y to that class of vises in which the movable jaw may be rapidly moved to adjust it approximately to the size of the work, and in which a screw is used for clamping it when so adj usted; and the invention consists in the peculiar construction, arrangement, and combination of parts, hereinafter more particularly described, and then-pointed out in the claims.

Referring now to the details of the drawings, A represents the xed jaw of the vise, in which works a slide, B, (see Fig. 5,) having on its under side a rack, C, and carrying with ita nut or female screw, D, which is preferably fitted into a slot, b, in the lower part of the slide and fastened there by a pin, d. The movable jaw E has its slideF tted to pass within the slide B, and is slotted, as shown in Fig. 3, to allow it to pass on each side of the nut D. At G is shown the screw, which is fitted and securedto the movable j aw in the ordinary manner, and is provided with the usual handle, g.

Fitted in a recess in the lower part of the fixed jaw is a rocking dog, H, having a portion cut away, as shown ath, and provided with a pin, h', which bears against one end of a spring, I, set in a curved recess, as shown in Fig. 2. At one end of the dog is a handle or lever, H', by which .the dog can be turned into the position shown by dotted lines in Fig. 2.

We deem it important that the slide F be bifurcated or recessed to receive the nut D, inasmuch as this enables us to make the vise much more compact than where the nut is located outside of the slide, as has been proposed.

vide the lower side of the iixed jaw with abase, J, having corrugationsj on a supplementary plate, K, provided with holes, through which may be passed screws or bolts L, to secure the same' to a bench, M. Attached to the center of base .I is a screw-bolt, N, which passes through the center of plate K, and is provided with va wing-nut, O, by screwing up which the base, plate, and bench are rmly secured together. It is obvious that by loosening said wing-nut the base, and consequently-the vise, of which it forms a part, may be turned in any desired position, and by screwing up the nut again it may be secured in said position. On the opposite ends of the slide B are a pin, P, and lug Q, which act as stops to prevent the slide moving too far in either direction.

The operation of the vise being obvious from the above description it is therefore unnecessary to give any detailed description of the If the vise is to be made to swivel, we prosame, and it will suffice to say that by turning the handle H and dog H into the position shown in dotted lines in Fig. 2 the movable jaw E and slideB can be readily and rapidly moved in either direction, so as to allow of the placing of any desired article between the jaws, and by allowing the spring-I to vact upon the dog the latter is turned, as shown in full-lines in Fig.'2, so as to catch in the rack C and hold the slide B fast, where, by turning the handle g and screw G, the article between the jaws will be clamped fast, as with the ordinary vise.

Fromthe above it will be seen that we have produced a vise that will not only have the ordinary screw-grip-so essential for some styles of work-but one which canl be rapidly adjusted to the different sizes of articles to be clamped therein, and which will, owing to the slide B, open much wider than the ordinary screw-vises.

Having thus shown one way of carrying out our invention, but without limiting ourselves movable and fixed jaws, and a nut for the screw, roe

connected to the intermediate slide and entering the recess in the fixed jaw, substantially as described.

2. The combination, with the fixed jaw A and thc movable jaw E, having a bifurcated slide, F, of the screw G, turning in said jaw E, the slide B, receiving the slide F of the movable jaw, the nut D, fixed in the slide B and entering the recess in the slide F, and the dog H, catching in a rack on the slide B, substantially as described.

3. The combination, with the fixed jaw A and the movable jaw E, having. a bifnrcated slide, F, of the screw G, turning in said jaw E, the slide B, provided with a rack on its under side and constructed to receive the slide F of the movable jam-the nut D, fixed in a. slot in the slide B and adapted to pass into the bifurcation of the slide F, the dog H, catching on the rack on the slide B, andthe spring I, acting on the dog, substantially as described.

In testimony whereof we aix ou r sign atures, V

in presence of two witnesses, this 30th day of March, 1887.
